Definition of language is not up to you but society in the aggregate.

You can claim as you wish while I and others can do the same.

If you're saying we need to hold to beliefs of the past, that's a position that physical reality makes untenable.

See you in church? That was the center of communal life for the majority for centuries. Anyone that's abandoned such agency has engaged in abandonment of history, of norms others can just as easily (and do) claim are more important than ever.

You can make whatever claims you want rhetorically but the non-fractal reality we live in does not allow for the strict conservatism you appeal for. Entropy gives rise to generational churn which gives rise to shifting social values.

These corny appeals to history you never directly experienced are little more than parroting grammatically correct statements you were taught.
